JS.TS.PREFER.NAMESPACE.KEYWORD
Require the use of the 'namespace' keyword instead of the 'module' keyword to declare custom TypeScript modules
In an effort to prevent further confusion between custom TypeScript modules and the new ES2015 modules, starting
with TypeScript v1.5 the keyword namespace is now the preferred way to declare custom TypeScript modules.
